We suggest a method that permits generation of a train of solitons with an arbitrary phase difference between adjacent pulses in a single-mode optical fiber. Specifically, a sequence of solitons in quadrature (i.e., where successive pulses differ in phase by π/2) can permit high-bit-rate transmission. It is shown that this train of pulses has advantages for use in optical transmission lines as a premodulated sequence of pulses because neighboring solitons in the train neither attract nor repel. The case in which this train of pulses is generated in an optical fiber with gain is also considered.
